- One of the arrays of keys is to be operated exclusively by the left hand, the other one exclusively by the right hand.
- the keyboard is fully bipartite i.e.
- the two arrays of keys are comprised in two parts freely movable relative to each other of the keyboard, so that the relative spatial position of the arrays of keys may be such as to meet optimally the actual needs given by the arm's length as well as the positions of arms and hands of an actual user.

- each key is combined with a contact mechanism, generating a spatial of key actuation as soon as the key is hit.
- the signal of key actuation usually activates a coding unit selected by the switching device; when activated by the signal of key actuation, the coding unit generates a specific code signal being recognized by the connected data processing facility, and causing the input of an alphameric or other character of the control of a function of the data processing facility.
- the key functions controllable by the respective keys it will be referred exclusively to the key functions controllable by the respective keys.

- the two parts of a keyboard are preferably movable relative to each other.
- the two parts of a keyboard are mechanically separated so that they can be placed arbitrarily relative to each other. Because of the mutual mobility of the two parts, they may be rotated arbitrarily relative to each other which eliminates a source of obstruction of the fingers occurring in conventional typewriters. Therefore the design according to fig. 1 and 2 is preferred.
- the two parts of the keyboard are surrounded by a border along three sides, namely along the right, the left and the upper edge, the border rising e.g. 4 cm over the surface of the keys.
- This border is to facilitate particularly the task of locating blindly the keys of the uppermost row which are, by experience, particularly difficult keys to be hit blindly.

- key 41 in fig. 2 and 4 (in the German keyboard the conventional ö-key) is used as a second shift key; key 41 corresponds to the initial position of the little finger of the right hand. In order to impair a reliable hitting of symbols displaced from key 41 as little as possible, the symbols are settled anew in an optimal way.
- the character "ö" is assigned to key 48 in fig. 2 and 4, which drives the hyphen and the underlining out of their traditional places.
- Underlining is now provided by key 48 when actuated in the third operational state of the keyboard (third level of designation); this is to be considered a progress, as in most cases, unerlining is combined closely with cursor movements to be controlled in the third operational state of the keyboard as well.

Abstract
Description
- This invention relates to a keyboard for entering data into a data processing facility, including a left and a right array of keys both having a number of data keys some of them having the functions of character, numeral and symbol keys, one of them being a space key and at least two of them first shift keys.
- The difficulty in attaining a high speed of entering data using conventional keyboards as shown e.g. in the German technical magazine ELEKTRONIK 11 / May 30, 1986,
page 18, is caused essentially by auxiliary keyboards including the function keys for moving a light point (in the following called "cursor") on a monitor or CRT screen, numeral keys ect., and being designated to be used in addition to a main keyboard essentially identical with one of the usual national standard keyboards for typewriters. Therefore a blind actuation of keys using the ten fingers is practically impossible; furthermore at least one hand has frequently to cover considerable distances. - Accordingly the object of this invention is to provide a keyboard for a data processing facility like a text editing facility and the like, capable of supporting a fast and after some training blind operation, and of being adapted easily to different working conditions and users.
- This object is achieved by the invention as characterized in the patent claims and described in greater detail in the following.
- This keyboard consists essentially of two arrays of keys both together including all the keys necessary for the input of data and the control of functions thus obviating any auxi liary keyboards slowing down the operation. All keys are easily accessible to a blind grip of the fingers. The extention of the arrays is limited to a minimum so that a displacement of frequently used symbols into the periferal zone of the keyboard is avoided, where it is known from experience to be particularly difficult to hit the keys reliably. One of the arrays of keys is to be operated exclusively by the left hand, the other one exclusively by the right hand. In a preferred design based on the invention, the keyboard is fully bipartite i.e. the two arrays of keys are comprised in two parts freely movable relative to each other of the keyboard, so that the relative spatial position of the arrays of keys may be such as to meet optimally the actual needs given by the arm's length as well as the positions of arms and hands of an actual user. In this connection it is e.g. possible to place a text to be copied in inclined position between the two arrays to keys in such a manner that the user can easily see the screen over the text. Furthermore it is conceivable to mount the two parts of the keyboard on top of the armrests of a comfortable chair like a deck chair, so that a user can manipulate data comfortably on a large screen or the like from such a chair.
- It is very obvious that these requirements cannot be satisfied by the usual assignement of coding units to the individual keys. Rather, it is necessary to make at least some of the keys couplable to more than the two conventional coding units. In the examples described in the following of a keyboard design based on the invention, some but not all keys can be coupled arbitrarily to one of four coding units, so that the keyboard correspondingly has four levels of designation. Actuating an additional, well placed shift key can be done much faster by a trained user than locating keys in auxiliary keyboards. In the following the invention is further illustrated by two examples of varying design with reference to the drawings, in which
- Figs. 1 and 2 are simplified plane views of a left and a right part of a keyboard, respectively, representing a first, preferred embodiment of the invention and
- figs. 3 and 4 are simplified plane views of a left and a right part of a keyboard, respectively, representing a second embodiment of the invention.
- The depicted exemplary embodiments are based on the German standard key assignement.
- In the following description of the invention it is assumed that each key is combined with a contact mechanism, generating a spatial of key actuation as soon as the key is hit. After having passed a contact bounce eliminator circuit and a switching device, the signal of key actuation usually activates a coding unit selected by the switching device; when activated by the signal of key actuation, the coding unit generates a specific code signal being recognized by the connected data processing facility, and causing the input of an alphameric or other character of the control of a function of the data processing facility. In the following, for simplicity, it will be referred exclusively to the key functions controllable by the respective keys.
- In the keyboard design according to fig. 1 and 2, the keys are arranged essentially in an orthogonal array, i.e. the keys align as well as in horizontal as well as in vertical direction.
- In the keyboard design according to fig. 3 and 4, the keys are staggered in adjacent horizontal rows as in the usual mechanical keyboards for typewriters having a fixed arrangement of keys.
- In both cases the two parts of a keyboard are preferably movable relative to each other. In particular the two parts of a keyboard are mechanically separated so that they can be placed arbitrarily relative to each other. Because of the mutual mobility of the two parts, they may be rotated arbitrarily relative to each other which eliminates a source of obstruction of the fingers occurring in conventional typewriters. Therefore the design according to fig. 1 and 2 is preferred.
- As a support for the beginner, the two parts of the keyboard are surrounded by a border along three sides, namely along the right, the left and the upper edge, the border rising e.g. 4 cm over the surface of the keys. This border is to facilitate particularly the task of locating blindly the keys of the uppermost row which are, by experience, particularly difficult keys to be hit blindly. From the
edges 52bundels screws 55 to 58 enabling the left and the right part of the keyboard to be joined rigidly by means of a bridge of arbitrary shape in an arbitrary geometrical arrangement. - For facilitating the adaptation of the user to the new bipartite keyboard, one of the national standard key assignements is adopted essentially unchanged (in the examples of figs. 1 to 4 it is the German key assignement) for two operational states of the keyboard (levels of designation). These first two operational states can be set by means of each of three
first shift keys key 41 in fig. 2 and 4 (in the German keyboard the conventional ö-key) is used as a second shift key;key 41 corresponds to the initial position of the little finger of the right hand. In order to impair a reliable hitting of symbols displaced fromkey 41 as little as possible, the symbols are settled anew in an optimal way. In the case of the German keyboard, the character "ö" is assigned tokey 48 in fig. 2 and 4, which drives the hyphen and the underlining out of their traditional places. Underlining is now provided by key 48 when actuated in the third operational state of the keyboard (third level of designation); this is to be considered a progress, as in most cases, unerlining is combined closely with cursor movements to be controlled in the third operational state of the keyboard as well. In order to facilitate the use of the hyphen during the usual typing of texts using the first and second operational state of the keyboard ( first and second level of designation) in the conventional way, the hyphen is assigned to key 30 in the first operational state;key 30 should be easily locatable by aid of theborder 52 mentioned above. - There is a
lamp 51 in the right part of the keyboard according of fig. 2 and 4 for indicating the second switching device beeing activated by thesecond shift key 41 ; when turned on, the lamp also indicates the active operational state of the second switching device. The second switching device controlled bykey 41 is bistable, and its design is such that each actuation ofkey 41 causes a reversal of the operational state of this switching device.Key 41 is of a preferably loud, e.g. red colour and is not labeled. All the other keys are preferably of a light colour (a light gray or light beige). In order to ensure thatkeys 41; 18, 49, and 12 have control of both parts of the keyboard at the same time, two additional signal lines are necessary leading from the right part of the keyboard to a point of convergence of the cables of the two parts of the keyboard and from there on further to the left part of the keyboard. Accordingly, either thedigital signal level 0 or 1 (=switching signal) is held on these signal lines at any time, and indicates, if the switching device concerned is in an activated operational state or at rest. - In the figures 1 to 4 the keys are labeled according to the proper coding functions effective in the different operational states to be set by using the three
first shift keys second shift key 41 . The operational state of the first switching device can be reversed bistably i.e. locked usingkey 12 , whereas thekeys switching signal 0,0). The second operational state S/O is set by actuating of one of thefirst shift keys switching signal 1,0). The third operational state R/U is with the first switching device being at rest and the second switching device in an activated operational state (switching signal 0,1). The fourth operational state R/O is with both switching devices being in an activated operational state (switching signal 1,1). The change between both of the conventional first operational states S/U and S/O occurs as in the past, when one of thefirst shift keys - It is advantageous, if a keyboard still offers some empty space for including further special symbols and/or functions. Therefore, at present, not all the keys are assigned to four coding units in this keyboard. The
keys - 1) a complete national standard keyboard,
- 2) all the additional symbols for programming e.g. in the computer language "Basic",
- 3) commands for the control of tabulator and row delimiter marks,
- 4) commands for cursor movements,
- 5) eight further control commands,
- 6) twenty programmable functions F0 to F19 .
- An easy control of the cursor was considered to be of great importance. Therefore, in this keyboard, the movement of the cursor is controlled by keys comprised in one of the two single arrays of keys of the keyboard and particularly by keys to be actuated exclusively and comfortably by the two
index fingers - In the examples of keyboards designed as shown in figs. 1 to 4 and based on the German standard key assignement, the different keys are used in the four different operational states S/U , S,O , R/U , and R/O , respectively, corresponding to the switching states 0,0; 1,0; 0,1; 1,1; respectively, and connected to the following coding units, identified by the object of the corresponding code signal and by the function controlled by the code signal, respectively:
